I'm pretty sure I ovulated today, however, I woke up this morning at 2:45am (normally 6:30am) and my temp was 97.6. I went back to bed at 5:00am and woke up 6:15am and it was 98.8? And I got a positive OPK today. Does any of this make sense? And how long does it take sperm to reach the fallopian tubes?
